Remove the outer leaves of the cabbage, cut it in half, and shred it finely using a sharp knife or a food processor.
Peel and shred the carrots using a grater. Thinly slice the red bell pepper and chop the green onions.
In a large mixing bowl, combine the shredded cabbage, carrots, red bell pepper, and green onions. If using, add the fresh cilantro for extra flavor.
In a small bowl, prepare the Asian dressing by whisking together the soy sauce, rice vinegar, sesame oil, honey or maple syrup, grated ginger, and minced garlic until well combined.
Pour the dressing over the vegetable mixture in the large bowl. Toss everything together until the vegetables are evenly coated with the dressing.
Let the salad sit for about 5 minutes to allow the flavors to meld. Before serving, sprinkle the toasted sesame seeds on top for garnish.
Serve chilled or at room temperature.
